Question

Which is the y-intercept of the line represented by the equation?

4x - 8y = 64
A. (8, 64)
B. (48, -8)
C. (16, 8)
D. (0, -8)

Answer 1

D. (0,-8)

Explanation:

Put the equation into slope/y-intercept format:

4x - 8y = 64

-8y = -4x + 64

y = (1/2)x - 8 [The y-intercept is -8; the value of y when x = 0]

D. (0,-8)
